Get the Run-stiff mug.
It's like everything you do, say or see is taking a toll on your health unneccessarily.

Friends seem to be 'extra-hard work to socialise with.

Like you are extra tuition learning for school and the teacher always marks your paper down or criticise your effort.

You try and please your girlfriend and buy her flowers but she thinks youve done something wrong and criticises you with suspicious remarks.

You dress smartly for an event but people call you a 'poof'
"Hey Bob, that car you brought was a lemon can't you buy anything decent"?

B:"When making buying decisions-feels like I'm always running into a stiff breeze"!
